SASH SEGURI-NG DEVICE Filed Oct. 11, 1953 INVENTORS WITNESSESlk/mwzdfe/zzm Zw za BY 2 5;? m/w WWATTORNY Patented Apr. 17, 1934 UNITEDSTATES PATENT OFFICE 3 Claims.

This invention relates tosash securing devices, and while we employ theterm sash securing devices and shall hereinafter describe a securingdevice in connection with a sash of the hinge type, it is to bedistinctly understood that the securing device may be used with any typeof door or analogous member which is to be secured in closed position.

An object of the invention is to provide a securing device in which thesash will be drawn tightly to the jamb and be secured by the positiveaction of the securing device through the medium of an. operating lever.

A further object is to provide a securing device of this character inwhich a lever handle is employed to control the movement of an operatinglever, the latter fixed to and adapted to turn a shaft having anydesired number of pressure dogs thereon so as to positively move thedogs to cause the sash to be drawn into the frame and against the jamband positively secure the sash in its closed position.

A further object is to provide a sash securing device which embodiesmany novel features of construction and combinations and arrangements ofparts, all of which will be more fully hereinafter described and pointedout in the claims.

In the accompanying drawing- Figure 1 is a fragmentary view in elevationillustrating my improved sash securing device;

Figure 2 is a view in section on the line 2/2 of Figure 1;

Figure 3 is a view similar to Figure 2 showing the device in releasedposition;

6 Figgre 4 is a plan view of the bearing bracket Figure 5 is a view insection through the supporting lmee 7.

1 represents a window frame or, more specifically, the jamb thereof, and2 a hinged sash of the outwardly swinging type. A vertical shaft 3 islocated adjacent the free edge of the sash and is turnably mounted invertical bearings or keepers 4, and on this shaft 3 any desired numberof pressure dogs 5 are rigidly secured, these pressure dogs beingadapted to engage the jamb or frame 1, as indicated.

A bearing bracket 6 is secured to the sash, and this bearing bracket,illustrated in detail in Figure 4, is of general arch shape so as tostraddle the shaft 3, and the ends of the bearing bracket are preferablyriveted to a supporting knee '7 which in turn is secured to the sash.The bearing bracket 6 has an integral axle 8 projecting therefrom onwhich an operating handle 9 is pivotally secured. The axle 8 is disposedhorizontally or perpendicularly with respect to the axis of the shaft 3.

We have illustrated the handle 9 as having a hearing 10, and haveillustrated the axle as being upset or enlarged at its end, as indicatedat 11, with suitable spacing washers 12 on the axle so that theoperating handle will be permanently attached to the axle or is free toswing thereon.

13 represents our improved operating lever, which is rigidly secured tothe shaft 3 and projects at right angles therefrom. This operating lever13 has an opening 14 therein which is in the form of a three-way openingshaped somewhat after the manner of a three-leaf clover, andtheoperating handle 9 has a finger 15 thereon which is engageable with thelever 13 by virtue of the opening 14, to act on the lever 13, and islocated at approximately right angles to the major portion of the handle9. For clearness of description the three-way opening 14 and theoperating lever 13 may be considered as comprising three communicatingrecesses or notches 16, 17 and 18.

In operation, the finger 15, which is cross-sectionally round in theform of a pin, moves from one recess or notch 16 into the notch 17, andvice versa, and during its passage from one recess 16 to the otherrecess 17 the finger 15 is accommodated in the recess 18, because ofthefact that such a recess is absolutely necessary as the operatinglever 13 in its movement defines a path with relation to the pivot oraxis thereof in its movement past dead center, which requires the shapeof opening or arrangement of recesses as above described. Furthermore,it will be noted that, by reason of the fact that this operating lever13 is moved past dead center in forcing the dogs 5 against the sash, thesecurement becomes a positive one and cannot be released by pressureagainst the sash, but can only be released when the operating lever isswung through its are past dead center, as above explained.

Further, it will be noted that the operating dogs 5 may engage the frameor jamb before the sash 1 is completely closed and thus draw the sash toclosed position while the operating lever 13 is being moved past deadcenter to a positive securing position; in fact, this movement may be atleast an inch or possibly more.

It is understood, of course, that our locking device can be used foreither wood or metal windows or doors, and can be produced more cheaplyand more efficiently than the old type Cremorne bolts. It will also benoted that the operating dogs are swung through an arc of approximatelyninety degrees so as to create a clear passage between the jamb andsash, and that the securing device is so simply constructed that it isnot apt to get out of order.

While we have illustrated what we believe to be the preferred embodimentof our invention, it is to be distinctly understood that various slightchanges may be made with regard to the form and arrangement of partswithout departing from our invention, and hence we do not limitourselves to the precise details set forth but consider ourselves atliberty to make such changes and alterations as fairly fall within thespirit and scope of the claims.

What we claim is:

1. A securing device, comprising a 'turnable shaft, dogs on the shaft,an operating lever on the shaft, a lever handle mounted to move in aplane at right angles to the operating lever, said operating leverhaving a three-way opening therein, and a finger on the lever projectingat an angle thereto and projecting into the opening in the projectinglever.

2. A securing device, including a shaft adapted to be supported inbearings on a sash, pressure dogs fixed to the shaft and adapted toengage the frame of the sash, an arched bearing bracket secured to thesash and straddling the shaft, an

axle on the bearing bracket, an operating handle pivotally supported onthe axle, an operating lever fixed to the shaft and extending at rightangles thereto, said lever having a three-way opening therein, and afinger on the operating handle projecting into the three-way opening ofthe lever and adapted, when the handle is swung, to move the operatinglever past dead center with relation to the finger, causing the fingerto move into recessed or oifset portions constituting parts of the leverand positively secure the dogs against movement except through themedium of the operating handle.

3. A securing device comprising a turnable shaft, pressure means on saidshaft, a radially disposed member on said shaft, said member having anopening therein consisting of three communicating notches, a leverhandle movable on an axis perpendicular to the axis of said shaft, and apin on said handle engaging said member by virtue of said opening toturn said shaft into a position in which said means will exert pressure,in response to the operation of said handle, the pin being received inone of said notches to prevent retrograde turning of the shaft from saidposition.
